Last night on the Late Show with David Letterman, Dave and Salma Hayek engaged in some first-time parent chatter about their toddlers, and apparently, little Valentina has some strange sleeping habits.

While Harry Letterman loves to wake his parents up at random times, Salma Hayek's daughter sleeps well but finds other ways to keep her mother up. "She has too much fun sleeping. She talks, she screams, she sings, she claps, she sleepwalks, she screams for Barney, she fights with someone," says Hayek. Dave then asks about Valentina's dad (Francois-Henri Pinault, who Hayek is on and off with) and demands, "who is this guy?"
